Did you know your body burns most of its daily calories while doing absolutely nothing? Basal metabolic rate (BMR) makes up roughly 60 to 70% of the energy you use each day (Cleveland Clinic, 2023). So it is smart to ask how to increase BMR naturally.
The honest answer is smaller than most blogs promise. But the real levers do work over time. This guide separates what actually moves your resting metabolism from what barely nudges it. Want the numbers for your own body first? Try our BMR and TDEE calculator, then come back here.
Put these numbers to work. Estimate your resting burn with our free BMR & TDEE Calculator, then set daily targets with the Calorie Calculator.
What Does It Mean To Increase Your BMR Naturally?
Your BMR is the energy your body spends at complete rest. It covers breathing, blood flow, brain activity, and cell repair. This baseline is about 60 to 70% of your total daily calorie burn (Cleveland Clinic, 2023).
Raising it naturally means supporting the systems that set that baseline. You cannot flip a switch and double your metabolism. Instead, you shift it upward slowly by keeping more lean tissue and moving more.
Here is what “naturally” rules in and rules out:
- In: building and keeping muscle, daily movement, and eating enough.
- In: steady habits that protect lean mass over months and years.
- Out: pills, teas, or “fat-burning” powders that promise fast jumps.
Age and sex also shape your baseline, and those factors deserve their own deep dive. For that context, see our definitive guide to basal metabolic rate.
What Actually Moves Your BMR?
Not every “metabolism hack” pulls the same weight. Activity beyond rest makes up roughly 20 to 30% of your daily calories, and food digestion adds about 10% (Cleveland Clinic, 2023). The levers you control most are muscle, movement, and protein.
The chart below ranks the real drivers from biggest to smallest. Notice the honest gap at the end. Green tea, supplements, and meal timing barely register next to muscle and daily activity.
How Does Building Muscle Raise Resting Metabolism?
Muscle is metabolically active, but the resting payoff is modest. Skeletal muscle burns only about 13 kcal per kilogram each day, or roughly 6 kcal per pound (Wang, 2001). So adding 2 kg of muscle raises your BMR by only about 26 kcal a day.
That number busts a popular myth. You may have read that one pound of muscle burns 50 calories at rest. It does not. The resting figure is closer to 6 calories per pound.
So why train at all? Because the real wins come from the whole package, not the resting spike. Lifting weights burns calories during and after the session. It also protects lean mass while you lose fat, which keeps your baseline from sinking.
Try these compound moves twice or three times per week:
- Squats and lunges for legs and glutes.
- Deadlifts and hip hinges for the back chain.
- Presses and push-ups for chest and shoulders.
- Rows and pulldowns for the upper back.
Add a little weight or a few reps over time. Progress is what keeps the muscle, and the muscle is what holds your baseline steady.
Why Does Daily Movement (NEAT) Matter So Much?
Movement outside the gym may be your biggest untapped lever. Activity beyond rest makes up roughly 20 to 30% of daily calories (Cleveland Clinic, 2023). Much of that comes from NEAT, the non-exercise movement you do all day.
NEAT stands for non-exercise activity thermogenesis. It counts walking, standing, fidgeting, chores, and taking the stairs. These small actions add up far more than one workout ever could.
Here is the useful part: NEAT is highly adjustable. Two people with the same BMR can burn very different amounts just from how much they move between tasks. Sit all day and that gap works against you.
Easy ways to raise your daily movement:
- Take a short walk after each meal.
- Stand or pace during calls and video meetings.
- Park farther away and use the stairs.
- Set an hourly reminder to get up and stretch.
None of this feels like exercise, and that is the point. Small movements repeated all day beat one heroic session you dread and skip.
How Much Protein Do You Need To Support Metabolism?
Protein does two quiet but valuable jobs for your metabolism. Digesting food burns about 10% of the calories you eat, and protein has the highest thermic effect of the three macronutrients (Cleveland Clinic, 2023). Protein also protects muscle while you lose fat.
That second job is the bigger deal. When you cut calories, some weight can come from muscle. Eating enough protein helps you keep that lean tissue, which keeps your baseline higher.
You do not need to chase a magic number. Spread protein across your meals rather than loading it all at dinner. A palm-sized portion at each meal is a simple, practical target.
Reliable protein sources include:
- Eggs, fish, poultry, and lean meat.
- Greek yogurt, milk, and cottage cheese.
- Beans, lentils, tofu, and tempeh.
Pair protein with strength training and the effect compounds. One preserves the muscle, the other builds it. Together they defend your resting metabolism better than either alone.
Why Does Under-Eating Backfire?
Eating too little for too long can work against your metabolism. Research shows adaptive thermogenesis is real, meaning the body can lower energy use during a long deficit (American Journal of Clinical Nutrition, 2022). It is a modest slowdown, not a full shutdown.
This matters for anyone trying to lose weight fast. Crash diets often strip away muscle, and less muscle means a lower baseline. So the very tactic meant to burn fat can chip at your metabolism.
The fix is not to stop losing weight. It is to lose it at a reasonable pace with enough protein and strength work. A moderate deficit protects lean mass better than an aggressive one.
A practical guardrail: avoid eating below your BMR for long stretches. Your BMR is a floor, not a diet target. To see your own numbers, run them through our BMR and TDEE calculator.
Do Metabolism-Boosting Foods And Supplements Work?
Most “metabolism boosters” deliver tiny or short-lived effects. Green tea, caffeine, and spicy foods can nudge calorie burn slightly, but the changes are small and fade quickly. Meal frequency does not change your 24-hour energy use at all (Cleveland Clinic, 2023).
Let us clear up the most common claims:
- Green tea and caffeine: a minor, temporary bump, not a lasting BMR change.
- Spicy food: capsaicin raises burn briefly, then it settles back.
- Eating every two hours: total daily food matters, not the number of meals.
- Fat-burner supplements: weak evidence, and some carry real safety risks.
Here is the reframe worth remembering. If a product promises a big metabolic jump, the science rarely backs it. The unglamorous levers, muscle and movement, quietly outperform every supplement on the shelf.

3 Evidence-Based Ways To Support Your Metabolism
You do not need a complicated plan to raise your baseline. Since activity and lean mass drive most of the difference, three habits carry the load (Cleveland Clinic, 2023). Follow the steps below in order.
Start with step one and add the next when it feels routine. Consistency beats intensity here. These habits protect lean mass and daily movement, the two things that keep your baseline up.

Frequently Asked Questions
Can You Really Increase Your BMR Naturally?
Yes, but the gains are modest and slow. BMR is about 60 to 70% of daily calorie burn (Cleveland Clinic, 2023). Building muscle, moving more, and eating enough protein nudge it upward and, just as importantly, stop it from falling.
How Much Does Building Muscle Raise Your BMR?
Less than most people expect. Resting muscle burns about 13 kcal per kilogram daily, roughly 6 kcal per pound (Wang, 2001). So gaining 2 kg of muscle adds only about 26 kcal a day. The bigger value is protecting lean mass and the calories spent training.
Do Green Tea Or Fat-Burner Supplements Boost Metabolism?
Only slightly and only briefly. Green tea, caffeine, and spicy foods cause small, short-lived bumps in calorie burn (Cleveland Clinic, 2023). Meal frequency does not change 24-hour energy use. Muscle and daily movement matter far more than any supplement.
Does Eating Too Little Slow Your Metabolism?
It can, especially over long periods. Adaptive thermogenesis is real, meaning the body lowers energy use during a prolonged deficit (American Journal of Clinical Nutrition, 2022). Crash diets also strip muscle, which lowers your baseline. Lose weight at a moderate pace instead.
